So I just tried to feed my new BP for the first time and no luck, he stayed out for about 30min on top of his hide and hovered over the mouse but just returned to under his hide after, the entire time he was above it with his head back and neck in a s shape (the "look") bet yet won't eat, He is 195 grams, 21 in long, 3 in in gerth. I went to pet land and got frozen large feeders (3 in in gerth) and I thawed it in hot water then warmed it with a blow dryer. I know he is under weight but should I be worried? Should I go get medium feeders or even small? They said he was roughly 6months old.
